4Application filed October 18, 1911. Serial No. 655,311.

To all whom t may concern:

Be it known that I, -Vroron M. SUMMA, residing at St. Louis, Missouri, and being a ctiz'en'of ,the .United States, have invented certain `new ,and useful Improvements in Car-,Roofs,1of whichthe following is a full,

clear, and exact description, such as will en-fl theart.

In said drawings: Figure 1 is a top plan view of a portion of a carroof constructed in,.accordance -with this .lnventi on, one-half of Said roof being illustrated with the roof v is a detail View, partly in section, illustrating the manner of attaching ,the l'ends of the carlines to the Wall plate.

The object of this invention is to provide a substantial roof st-ructure comprising a minimum lnumber of parts, and each of said parts vbeing of simple design .for facilitating ease of manipulation.

A further object is to so dispose the connections between the several roofing plates,

and between the roofing plates and the purlins, that the adjacent portions of the plates will serve to greatly reinforce the purlins and thus .render .possible -theuse of purl'ms of less cross sectional area than lwould be otherwise required.

Referring tothe drawing, the numerals l-l indicate the side posts of the car structure yand 2-2 the sheathing plates applied to .the outer .faces thereof. The longitudinallyextending side plates as 3 3, fixed to the upper ends of the posts l. may comprise any desired cross section but are preferably of Z shape, being disposed with their webs' horizontal and with inner flanges l upstanding from said webs, `and with outer flanges 5 depending. The upstanding flanges 4 are preferably fixed to the outer faces of the up per edges of the sheathing plates 2 by through rivets, some of which extend through the flanges of posts l.

The carlines 66 are illustrated as comprising simple angle sections, each with one of its flanges disposed horizontall and its other flange depending. Said carlines may however, be formed of any desired cross section. Each of the carlines extends continu? ously from side Wall to side wall, being bent at its middle point for inelining its opposite ends downwardly as is customary. The opposite end portions as 6-6fL extend over and beyond the `upper edge of the sheathing plates 2 and are bent vertically downward,

outside of said plates, sothat their extreme ends rest squarely upon the upper surfaces ofthe Webs of the side plates 3. One of their flanges is extended and bent to a horizontal as at 7 `and riveted to the upper surface of the side plate. Qnly two purlins are employed and these as 8-8, are fixed to the carlines at points spaced equi-distant upon opposite sides of the longitudinal median line of the roof. Euch of the purlins 8 comprises an angle section disposed with a substantially horizontal flange fixed to lthe upper surfaces of the horizontal flanges of the carlines, and a substantially vertical flange upstanding from the inner edge of said horizontal flange. The roof is thus divided lon gitudinally into three sections, each section being adapted to he covered by an independently formed, longitudinally extending, roof plate sect-ion; a central roof platel section 9 being disposed for covering the space between the purlins, and side roof plate sections 10-10 being disposed for covering the space between the purlins and the adjacent side plates 3.

The roof plate .sections 10 have their opposite longitudinal edges fixed to the purlins Sfand to the side plates 3 respectively. The inner longitudinal edge of each of said roof plate sections is extended across the upper surface of the horizontal flange of the adj acent purlin and is bent into au upstanding flange 1 0 fixed to the outer face of the upstanding flange of said purlin. longitudinal edges of each of the roof plate The outer dinal edges thereof bein sections ll() is bent or flanged downwardly to correspond to the curvature of the carlines .and is extended beyond the ends ofsaid oar lines-and is xed to the outer faces of the depending flange 5 of the adjacent side plate 3.

.The central section of the roof is of in-l l()a of the side roof plate sections 10 by through rivets extendmg through the upstanding Hanges of the purlins.

intermediate its longitudinal edges the roof plate section9 is preferably bowed upwardly from edge to edge for strengthening said plate.

At intervals along the length of the car are U shaped running board saddles as 11-11. These saddles span the roof plate section 9 and the opposite legs thereof de` pend and are fixed to the outer faces of the upstanding flanges of the purlins by rivets extending through the intermediate Bauges 9? 10a of the roof plate sections. 'lhe usual running boards as 12-12 are fixed to the upper surfaces of the saddles 11 and extend longitudinally abovey the section 9, being spaced therefrom. The lapping, substantially vertical, flanges of the plates 9 and 10 extending from end wall to end wall of the car, being rigidly fixed together throughout their length, materially assist the purlins in sustaining the roof against sagging in- I termediat'e its length. Ilhe posts 1 of the car wall are preferably extended above the upper` edge of the sheathing plates `2 and side plates 3 and are fixed to the depending flanges of the carlines, as at la, for st-rengthfV ening the connection between said carlines and wall.- Y l y It `will be obseryedthat the central roof plate section 9 is spaced above the central portions of the carlines. At the end of the car said roof plate section is extended be yond the vertical plane of the end wall 2a A(see Fig. 4r) and is curved downwardly as at 13 so as to lap theforward edge of the out.-

l standin flange 14 of the "end carline of the car. 'T e bent portion 13 covers the angeI 14in (such manner as to eflectually prevent theentrance ofrain or sleet, but is spaced sufficiently from said Harige so as to permit .of the free passage of air into the ca r for ventilation. 4
